This Chronomtre Souverain is quintessentially an F.P Journe in both its design language and movement. Housed in a classical 40mm dress watch case, it is made distinctive by F.P. Journes signature flat crown with a rope like pattern.

This example, is one of few pieces from the Black Label series, created exclusively for existing F. P Journe clients. Only twelvepieces are received by theboutiques in any year, with just two pieces for each model in the collection.

The black dial has a hobnail, Clous de Paris pattern in the centre, while the outer track holds the embossed decorative Arabic numerals. The signature F.P. Journe style hands are polished steel, matching the dark tones of the dial. Between 7 and 8 oclock, is a subsidiary seconds, with a power-reserve indicator at 3 o'clock, showing 56 hours. Overall, the dial layout is cleanly designed and highly-legible.

An interesting aspect of this timepiece lies in the power reserve, as when winding, instead of the indicator heading from 0-56, it goes the other way towards 0. This was deliberate by F.P. Journe, who borrowed this from marine chronometer clocks. The reasoning behind this lies in the idea that the power reserve indicator on this Chronomtre Souverain is not meant to tell you how many hours there are left, but instead how many hours since you have wound the watch.

While this piece is undeniably attractive, it is the movement that F.P. Journe is famed for. Part of the manual-winding , it is certainly independent haute horlogerie at its finest, as the in-house, Calibre 1304 is made entirely of 18k rose gold seen through the sapphire caseback. The movement has two mainspring barrels in parallel, which work together, powering the movement.

Most impressively, is the chronometric balance fitted into the movement, which helps to provide the accuracy that F.P. Journe has based his watchmaking around.As explains thusly:

"Chronometrywas invented by the 18th century English and French watchmakers, when their respective governments organised a competition that would reward the first watchmaker capable of making a timekeeper that could be carried on board a ship."

The hand-finishing is expertly conducted, mixing a combination of circular graining with sunburst and wave patterns. All screw heads are polished and all edges neatly chamfered with a Cte de Genve motif on the bridges.

In 2005, the Chronomtre Souverainwon the Favourite Mens Watch award the GPHG (Grand Prix dHorlogerie de Genve), the most prestigious award ceremony in the watch industry. Since then the has seen a number of dial variations but itsattraction has not faded.

This watch comes on astrap with curved-ends (measuring 20 x 19mm) and its original platinum tang buckle. The originalF.P. Journe black alligator strap is also supplied.

Viewings can be arranged in Central London by appointment.
